	<description><![CDATA[<p>SyRI is a comprehensive tool for predicting genomic differences between related genomes using whole-genome assemblies (WGA). The assemblies are aligned using whole-genome alignment tools, and these alignments are then used as input to SyRI. SyRI identifies syntenic path (longest set of co-linear regions), structural rearrangements (inversions, translocations, and duplications), local variations (SNPs, indels, CNVs etc) within syntenic and structural rearrangements, and un-aligned regions.</p><p>Address of the bookmark: <a href="https://schneebergerlab.github.io/syri/" rel="nofollow">https://schneebergerlab.github.io/syri/</a></p>]]></description>

	<description><![CDATA[<p>I will be doing NGS in the course of my research work and I will like to learn a programming language which is compatible with most bioinformatics tools or software. I basically want to do de-novo assembly, map reads, align reads, and expression analysis. Recommendations welcomed. Which languages would you recommend to a student wishing to enter the world of bioinformatics?</p>]]></description>

  <title><![CDATA[Postdoc in Genomics of Pipefishes and Seahorses at NSF-funded postdoctoral project in Adam Jones' Lab]]></title>
  <description><![CDATA[
<p>An NSF-funded postdoctoral position is available in Adam Jones' Lab<br />at the University of Idaho to study the evolution and development of<br />the male's brood pouch in syngnathid fishes (seahorses, pipefishes<br />and seadragons). The project is being conducted in collaboration<br />with Dr. William Cresko's group at the University of Oregon. The<br />postdoc will be involved in studies of comparative genomics across<br />the family Syngnathidae, investigations of brood pouch morphology, and<br />characterization of the brood pouch microbiome. The position will be<br />funded for two years, with the possibility of a third year. The postdoc<br />will be based at the University of Idaho and will interact extensively<br />with the Cresko Lab at the University of Oregon.</p>

<p>The University of Idaho is in Moscow, a small college town located in<br />Northern Idaho on the Washington border. Moscow is widely considered to<br />be a great place to live, and it's known for a pleasant downtown, active<br />farmer's market, and nearby recreational opportunities. All of Moscow<br />is within biking or walking distance of the University of Idaho. For<br />more information about Moscow, see https://visitmoscowid.com/.</p>

<p>The University of Idaho has very strong faculty in evolution and<br />genomics in multiple departments and interdisciplinary programs. Of<br />particular note are the Bioinformatics and Computational Biology<br />Program (BCB: https://www.uidaho.edu/sci/bcb/people/faculty) and<br />the Institute for Bioinformatics and Evolutionary Studies (IBEST:<br />https://www.ibest.uidaho.edu/index.php). In addition, the University of<br />Idaho is only eight miles from Washington State University in Pullman, and<br />faculty from the two institutions interact and collaborate extensively.</p>

<p>Minimum qualifications include: a Ph.D. in biological sciences,<br />bioinformatics, or a related discipline; experience conducting research<br />in genomics or evolutionary biology, as evidenced by publications<br />in peer-reviewed journals; and evidence of strong written and oral<br />communication skills.  Experience analyzing next-generation sequence<br />data and familiarity with the genomics of marine fishes are desirable<br />but not required.</p>

<p>Apply at: https://uidaho.peopleadmin.com/postings/30003</p>

<p>Review of applications will begin January 15, 2021. The start date<br />is flexible.</p>

<p>The University of Idaho is an equal opportunity/Affirmative Action/equal<br />access employer.</p>

<p>Informal inquiries are encouraged and can be directed to Adam Jones<br />(adamjones@uidaho.edu).</p>

	<title><![CDATA[Understanding RNA-Seq Normalization Methods: TPM vs. FPKM vs. CPM]]></title>
	<description><![CDATA[<p>RNA sequencing (RNA-Seq) is a powerful technology used to study transcriptomes, providing insights into gene expression levels. However, raw RNA-Seq data requires normalization to account for sequencing depth and gene length, enabling accurate comparisons between genes and samples. Among the most widely used normalization methods are TPM (Transcripts Per Million), FPKM (Fragments Per Kilobase Million), and CPM (Counts Per Million). Each method has its unique principles and applications, which we&rsquo;ll explore in this blog.</p><h2>Why Normalize RNA-Seq Data?</h2><p>Normalization is a crucial step in RNA-Seq analysis for the following reasons:</p><ul>
<li>
<p><strong>Sequencing depth:</strong> Different RNA-Seq experiments produce varying numbers of reads, making direct comparisons between samples misleading.</p>
</li>
<li>
<p><strong>Gene length:</strong> Longer genes inherently generate more reads, irrespective of their actual expression level.</p>
</li>
<li>
<p><strong>Bias reduction:</strong> Normalization mitigates technical biases, enabling meaningful biological interpretation.</p>
</li>
</ul><h2>TPM (Transcripts Per Million)</h2><p>TPM measures the proportion of reads mapped to a transcript, normalized by transcript length and sequencing depth. It is calculated as:</p><h3>Key Features:</h3><ol>
<li>
<p><strong>Proportionality:</strong> TPM values sum to 1,000,000 across all transcripts in a sample, making it easier to compare between samples.</p>
</li>
<li>
<p><strong>Intuitive interpretation:</strong> TPM values directly represent the abundance of transcripts in a sample.</p>
</li>
<li>
<p><strong>Preferred for comparisons:</strong> TPM facilitates between-sample comparisons better than FPKM.</p>
</li>
</ol><h2>FPKM (Fragments Per Kilobase Million)</h2><p>FPKM normalizes read counts by transcript length and sequencing depth, but without enforcing proportionality like TPM. It is defined as:</p><h3>Key Features:</h3><ol>
<li>
<p><strong>Historical significance:</strong> FPKM was one of the first normalization methods used for RNA-Seq.</p>
</li>
<li>
<p><strong>Single-end vs. paired-end:</strong> In paired-end sequencing, FPKM becomes RPKM (Reads Per Kilobase Million).</p>
</li>
<li>
<p><strong>Limited utility:</strong> FPKM values are not as robust as TPM for cross-sample comparisons due to lack of proportionality.</p>
</li>
</ol><h2>CPM (Counts Per Million)</h2><p>CPM normalizes raw read counts by sequencing depth, without considering gene length. It is expressed as:</p><h3>Key Features:</h3><ol>
<li>
<p><strong>Simplicity:</strong> CPM is straightforward and computationally less intensive.</p>
</li>
<li>
<p><strong>Application:</strong> Suitable for non-length-dependent analyses, such as comparing total expression levels or differential expression analysis.</p>
</li>
<li>
<p><strong>Gene length agnostic:</strong> CPM does not correct for gene length, making it less ideal for measuring expression levels.</p>
</li>
</ol><h2>When to Use Each Method</h2><ul>
<li>
<p><strong>TPM:</strong> Best for comparing expression levels between samples, especially when transcript length and sequencing depth vary.</p>
</li>
<li>
<p><strong>FPKM:</strong> Useful for historical consistency but generally replaced by TPM.</p>
</li>
<li>
<p><strong>CPM:</strong> Ideal for differential expression analysis when gene length normalization is unnecessary.</p>
</li>
</ul><h2>Conclusion</h2><p>Choosing the right normalization method depends on the specific objectives of your RNA-Seq analysis. TPM&rsquo;s proportionality and robustness make it the preferred choice for most applications, while CPM serves well for differential expression studies. Although FPKM paved the way for RNA-Seq normalization, it has largely been supplanted by TPM in modern workflows. Understanding these methods and their nuances ensures accurate and meaningful interpretations of RNA-Seq data.</p><h3>References:</h3><ol>
